HOT-WATER TANK.

SPECIFICATION forming part of Letters Patent No. 679,107, dated July 23,1901.

Application filed December 28, 1900. Serial No. 41,391. (No model.)

To all whom it may concern.-

Be it known that I, HENRY ALONZO BUCK, engineer, a citizen of the UnitedStates of America, and a resident of West Stafford, Connecticut, atpresent residing at 37 Fruchtstrasse, Berlin, Germany, have invented newand useful Improvements in Hot Water Tanks, of which the following is aspecification.

My invention relates to a new form of a hotwater tank which is used incombination with the condenser-pump, so that even the last quantities ofsteam are condensed and used for the purpose of heating the freshwater.

The new tank forming the object of my in- .vention differs from thosetanks known till now in that it is totally closed and its cover beingprovided with a vertical tube within which the vapors condense by comingin contact with the cold water flowing downward into the tank. By my newconstruction the drawback of the tanks now in use is done away with,which drawback consists in that they continuously emit vapors, whichmeans a loss of heat and becomes detrimental to the rooms and mechanismin the neighborhood of the tank.

I have shown in the accompanying drawing my water-tank in sideelevation.

a is the tank which contains the hot water and which may be providedwith a gage-glass b. The water is conducted into the tank by a tube 0and flows down through the long vertical tube cl, as indicated by thearrows c. The interior of the tube d may be shaped in such a manner thatthe down-flowing water offers a large contact-surface to the vaporswhich ascend within the tube 01 in the direction of the arrows c. It isevident that the fresh water from the tube 0 must condense completelythe vapors of the water-tank which ascend through the tube (1. The upperpart of this tube d communicates into a tube e, leading into theatmosphere. The water is taken from the tank through the pipe f, whichleads to the boiler-feed pump. Besides that, the tank has an inlet-tubeg, through which enter the hot water and the vapors from thecondenserpump. These vapors consist of steam and atmospheric air, and itis evident that all the steam is condensed in the tank and in thevertical tube cl, while the air will pass through the tube e, which mayopen into the atmosphere.

Having now particularly described and ascertained the nature of myinvention and the manner in which it may be performed, I declare thatwhat I claim is- 1. In a condenser, the combination with a tank, aninlet entering the top of said tank for conveying steam and hot waterthereto, and a water-outlet at the bottom of said tank; of a verticalstand-pipe entering the top of said tank, a coldwater pipe entering saidstand-pipe at the top thereof provided with means for condensing thevapors within said pipe, and an outlet communicating with the top ofsaid stand-pipe, substantially as described.

52. In a condenser, the combination with a tank, an inlet entering thetop of said tank for conveying steam and hot water thereto, awater-outlet at the bottom of said tank, and a gage-glass at one end ofsaid tank for indicating the height of water therein; of a verticalstand-pipe entering the top of said tank, a cold-water pipe enteringsaid stand-pipe at the top thereof provided with means for condensingthe vapors within said pipe, and an outlet communicating with the top ofsaid stand-pipe, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY ALONZO BUCK.
